摘要： A USB hub device having functionality of self firmware updating is disclosed. The USB hub device is integrated in a host electronic system, and comprises an upstream port, a plurality of downstream ports and a hub module comprising a plurality of second USB controller units. On the other hand, the host electronic system has a second USB controller unit. After one electronic device is coupled to one downstream port, the first USB controller unit sends a detection signal for verifying whether the electronic device includes at least one firmware update data or not. In case of the electronic device being verified to have the firmware update data, the hub module transmit the firmware update data from the electronic device to a memory unit thereof, thereby completing a firmware update of the USB hub device.

摘要： A host-to-host chip includes: first and second ports coupled to first and second hosts respectively; and a host-to-host control circuit coupled to the first port and the second port. When the host-to-host chip is coupled to the second host, the host-to-host control circuit identifies whether the second host is an i-Phone or an Android smartphone. If the host-to-host control circuit identifies that the second host is an i-Phone smartphone, in response to a command from the host-to-host control circuit, the second host switches to host role from device role, and the host-to-host control circuit controls whether data is transmitted between the first host and the second host via a DMA path. If the host-to-host control circuit identifies that the second host is an Android smartphone, the host-to-host control circuit determines that data is transmitted between the first host and the second host in a pass-through mode.

摘要： A USB hub includes an upstream port; a first USB device control unit for performing packet format conversion; an FIFO circuit for storing data outputted from the first host; a second USB device control unit for performing packet format conversion; and a plurality of downstream ports. When any one of the downstream ports is coupled to the mobile device, if the first host commands the mobile device to switch to a host role from a device role, the mobile device temporarily disconnects from the USB hub, and the first host commands the USB hub to change an internal routing path. After the mobile device switches to the host role, the first host still performs the host role, and the first USB device control unit performs the device role; the mobile device performs the host role, and the second USB device control unit performs the device role.
